Throughout the drawings, the light crossed lines of the various shafts indicate bearings therefor.

The entire machine is mounted on a main base or platform I, preferably in the form of a unitary casting, having two vertical side frame members 2 and 3 secured thereto. The machine may be driven by any suitable source of power, such as an electric motor 4 mounted on the platform i by the intermediary of a small base or table 5, Fig. 3,. suitably secured on the platform I. All the various mechanisms and operating parts of the machine are driven by the motor 4 and also all the various parts of the machine, both those that are driven as well as those that are stationary, are directly mounted on the platform I or are mounted in the side frame members 2 and 3, except for a number of minor supporting elements or braces.

Calendar jeed device The calendars 6 to be successively rolled and wrapped are placed on the fixed table I, Fig. 3,

The calendar is then moved on the rocable on the frame members in a horizontal plane by means of a pair of links l8, each connected to a short link II to the outer side end of the table, Fig. 5.. The other or inner side end of the table has a plurality of pusher fingers 12. preferably two. secured on the feed table 8, which are adapted to contact or positively grip the metal binding II of the calendar, between one side of the binding and the lowermost of the paper sheets of the calendar, to push or force the calendar into the rolling or winding mechanism, to be described hereinafter. For this purpose, each pusher finger l2 has a forked end M which grips the binding l8 as described. The feed table 8 also has a guide bar I5 at each end. each bar I8 having a spring pressed ball and socket member 18, Figs. 3, '1 and 27, to which is secured a pair of slightly wedge-shaped floatin guide bars l1 with guide fingers l8 for the ca endars.

The guide fingers i8 guide the calendars to be rolled between the guide bars I1 which latter are slidably mounted on the bars I5 so that both the table 8 and bars l1 have a floating action in a horizontal plane during feeding of a calendar and retraction of the table and bars after a feeding step.

Wrapping paper feed device The mechanism for preparing and feeding the sections of wrapping paper 28 is illustrated particularly in Figs. 1, lb, 8, 11, 24 and 25. The wrapping paper preparing device, including the adhesive and string applying devices, are mounted on and between two side frames l9 mounted on and secured at right angles in spaced relation to each other to the frame member 2. The wrapping paper sections 28, Figs. 24 and 25, are cut from the roll 2i, from the latter of which the paper unrolls as a web 22, Figs. 1 and 1b, and passes over the rollers 23 and 24. As the web passes over the roller 24 it receives a number of sections 25 of adhesive adjacent one edge of the paper web and a single line of adhesive 28 spaced a slight distance from the sections 25,

Figs. 8 and 11. The adhesive is supplied from a suitable source, such as the container 21, from which the adhesive is drawn up on the feed roller 28, Fig. 11, and transferred to the applicator rolls 29, the excess adhesive drawn up by the roller 28 being scraped off by blades 38 back into the container 21.

The web 22 of paper with the longitudinal sections 25 and 28 of adhesive proceeds over further feed rollers 8|, Figs. 1 and lb, to the main feed roller 82 having a cooperating felt roller 38 thereabove which is spring pressed and between which rollers 82 and 88 the web passes to the knife 84 which latter cuts the web against the support means 58 into the proper length so that the paper sections 28, Figs. 24 and 25, can then be fed by the endless belt 54 to a position to be fed into the partially rolled calendars. Just before the web reaches the rollers 82 and 33 a tearing string 35 is fed on to the adhesive line 28 from a spool, Fig. 1, by means of the roller 81.

The main roller 82 has a small gear wheel 88 mounted to rotate freely on the shaft 42 on one end and a larger gear wheel 88 securely mounted on the shaft 42 on the other end, Fig. 8, and i roller 82 is intermittently driven by the ge r sector 48 meshing with the gear 88. Since the roller 82 must only rotate in one direction, and

intermittently to feed the paper web, as will be explained, a one way clutch 4i, Fig. 12, is mounted on the endof the shaft 42 adiacentthe gear 88 so that in one direction of rotation of the sector 48, the clutch will rotate the shaft 42 to drive the roller 82, whereas in the other directio the clutch will be disengaged.

The gear wheel 88 meshes with and rotates a train of gears 48, Figs. lb and 11, to operate the adhesive applying means and to unroll the web 22 from the roll 2 I. v

Since the machine operates intermittently,'as

will be described hereinafter, suitable means should be provided to act as braking means to maintain the paper web 22 taut so that the revolving parts of the paper feed may be intermittently stopped without creating a slack in the web at any point of its travel. For this purpose, a friction brake 44, Fig. 1, may be provided on the shaft of the feed roller 45 for the paper roll 2|, also another friction brake 48, Figs.'1 and 8,

. Referring now to Figs. 24 and 25, the wrapping paper sections 28, each cut to the desired and proper length to completely wrap the calendars 8, travel over and to a feeding plate or table 41 by means of the endless belt 54, Figs. 24 andv 25 showing a wrapping paper section 28 infp'osition against an adjustable stop 48 on the plate and ready to be moved into a partially rolled calendar, Fig. 15, as will be explained herein- The plate 41 is hinged by means of depending lugs 49 to the frame members 2 and 8 after.

and the horizontal position and tilting of the plate to feed the wrapping paper is automatically controlled by the arm 5| secured at one end to the plate and controlled by the roller 52 on the arm 2l8 as will be explained hereinafter.

The plate 41 is also provided with a side guide rail 58, Figs. 24 and 25, integral therewith against which the adhesive side edge of the wrapping paper 28 slides while the latter is fed intoposition against the stop 48 by means of the feed belt 54 and with the aid of the arms 55. The

arms 55 hold the wrapping paper sections 28 on the belt 54 so that the sections of paper will be brought to the precise position to be fed into the partially rolled calendar, Fig. 15, as will bearplained hereinafter.

As the roller 52 is lowered, thereby permitting the table to tilt clockwise, Fig. 24, to feed a' sheet of wrapping paper 28, a cam 58 will rotate a lever 51 around its pivot 58, the latter being mounted, to the frame member 8. A short link 59 connects the free end of lever 81 to a rod 84 which latter is rotatably mounted on the plate" at V8! and to the side guide rail 58 at 88. A pair of short arms 81 are mounted in spaced relation.

wrapping paper so that the two pins I0, passing through slots II in the plate 41 and rail 53 will contact the edge of the wrapping paper 20 adjacent the adhesive section and positively move it off the plate in a direction at right angles to the direction of its feed movement onto th plate, to ultimately feed it into a partially rolled calendar, Fig. 15. 8

Figs. 24 and 25 also show the drive, such as the cord or cable 12, to drive thebelt 54 by means of the belt pulley I85 and small pulleys 250 and the drive shaft 25I. The belt 64 is maintained taut by means of an idler roller 252, Fig. 4, which is under tension by any suitable means.

The stop 48, Figs. 24 and 25, is adjustably mounted on the plate 41 by means of the slot 253' and bolt 254 to properly adjust the paper section 20 to properly feed it into the partially rolled calendar or to adjust the position of the wrapping paper sections if a wider or narrower calendar is to be wrapped.

Winding reel The winding reel 60, in which the calendars I are rolled and wrapped and the wrapper pressed to the adhesive, is illustrated in Figs. 1a, 3 and composed of two spaced frame discs 62, mounted to rotate with the shaft 6|, and a plurality of rolling rods63 of which in the example illustrated, six are included, although any suitable number may be employed.

Each rolling or winding rod 63 is provided with a longitudinal slot or groove 14 to receive the metal binding I3 of the calendar 6 to be rolled thereon, Fig. 21, as well as a key member I5 in the extended bearing sleeve 16 of the gear 11, Figs. 9, 20 and 21. One end of each rod 63 has a slightly levelled or cone-shaped end I8 and a button or head member 19 rigidly secured on the other end. When the rod 63 is in its retracted position, Fig. 20, it projects into and rotates in the receiving sleeve 80 mounted in one of the discs 62. Each sleeve 80 has a funnelshaped cut out portion 8| integral therewith to guide its rod 63 therein upon its retraction, as will be more fully explained hereinafter.

Also, each rolling rod 63 is provided with a pressure rod 82 and a counterpressure rod 83,

the latterof which consists of a plurality of spaced collars 84 securely mounted on a shaft 85, Fig. 20. Each rod 82 and 83 is mounted on a lever 86 pivoted at its inner end 86 to one of the discs 62, the rods 82, 83 being mounted in said levers, either in a fixed or rotary relationship, preferably the latter. As seen in Fig. 3, there are two levers 86 pivoted in pairs in spaced relation radially around each disc 62 and the six double pairs of levers 86, one double pair for each rolling rod 63, are maintained in the radial positions by means of a spider frame 81 securely mounted on the shaft 6I, Fig. 19, to rotate therewith andwith the discs 62. Each side lug 88, Fig. 20, ofthe spider frame 81 has two opposing springs 89 each adjustable as to tension on the bolt 80 in'order to urge each pair of rods 82 and 83 toward each other, Fig. 3, on diametrically opposite longitudinal contact lines relative to its respective'rolling rod 63. Also, each opposing pair of levers 86 is provided with a cam rod 8i, Figs. 3, 10 and 19, provided with a cam member 82, one for each pair of levers 86, and an actuating finger or cam 83, Fig. 10, on one end of Ill the rod 8I. This finger 83, upon rotation of the winding reel, is adjusted to strike a stationary abutment or curved plate 84, Figs. 14a and 19, mounted on the frame member 2 by means of a pair of rods 85'and which is in the circumferential path of the fingers so that upon striking such abutment, the particular rod H and its two cam members 82 will be rotated slightly so that the latter will spread the levers, 86' and they in turn the rods 82 and 83, apart to release the rolled and wrapped calendar, as will be explained hereinafter. As shown in Fig. 3, other than in the calendar ejecting or releasing position at 85, when the fingers 83 are not in contact with the abutment 84, the cam members, 82 will be parallel to the levers 86 but when the rods 82 and 83 are spread apart as shown at 85, the cam members 82 are at right angles relative to the rods 82 and 83. Thus the abutment 84 is mounted on the frame member 2 at such location in the circumferential path of the fingers 83 where it is desired to release the rolled and wrapped calendars. I

The right hand disc 62, Figs. 19 and 14, has a ratchet wheel IOI suitably secured thereto by such means as the bolts 86 whichlatter also comprise the pivot points for the levers 86 mounted on the opposite side of the right hand disc 62. A spring-pressed pawl member I02, Fig. 14, for the ratchet wheel IOI is mounted on a rocker arm I03 which latter-is freely rotatable on the shaft 6I of the winding reel by means of a bearing I04. This bearing I04 and the rocker arm I03 are mounted on the shaft 6| between the ratchet wheel IN and the frame member 2. Fig. 19, and on the other side of theframe member 2 a locking disc I05 is securely mounted on the shaft 6I by suitable means such as the pin I06. This locking disc I05 has as many notches or cut out portions I01 in its periphery as there are rolling rods 63 in the winding reel, namely, six. Two levers cooperate with the notches I01 of which one spring pressed lever I08, pivotally mounted in the frame member 2 at I09, Fig. 19, acts to prevent rotation of the winding reel in clockwise direction and therefore only in the direction of the arrows, Fig. 14, whereas the other lever I I0 acts to lock the winding reel each time it makes a stop to receive a calendar and wrapper to be rolled in one winding rod 63 and simultaneously to eject and release a rolled and wrapped calendar from another winding rod. The locking lever III] is provided with a rightangle hook member III, Fig; 14, which projects into the notches I01. The operation of these elements will be more fully described hereinafter.

On the outside of the left hand disc 62.-Fig, 19, of the winding reel 60, a large gear wheel H2 is mounted to rotate freely on the shaftv 6I and this gear meshes with the gears 11 mounted on the winding rods 63. The gear I I2 has an extended bushing II3 forming a bearing for the actuating gear II 4 mounted to rotate thereon, the latter being integral with or secured to a pawl lever II5, Fig. 5, havinga spring-pressed pawl II'6 pivotally mounted on the end thereof. The pawl II6 cooperates with a ratchet member III, Fig. 19, integral with the gear H2 and a toothed rack bar II8 meshes with the gear II4 which rotates the lever H5 and pawl I I6 in both directions upon the reciprocating motion of the rack bar II8 but the ratchet I I6 rotates the gear H2 in only one direction. The bushing II3 has a bearing surface in the frame member 3, Fig, 19,

and extends beyond said member 8 to the left on which a locking disc I I9 is secured having a notch I20, Fla. 5, in the periphery thereof. The cam 99, Fi s. 19 and 24, is secured to the disc H9 and cooperates with a roller IN on the lever 9i. This cam 99 actuates the feed table 41 for the wrapping paper sheets 20 and upon each succesaive rotation of the sear iI2 the proiecting ,portion I22, Fig. 2a, of the cam 99 strikes the roller I2I to rotate the lever 61 around its pivot 99 to successively feed a sheet of wrapping paper, that is upon each rotation of the winding rods 69. A sheet of wrappilm paper is fed into the partly wound calendar, Fig. 15, which is adjacent the feed plate 41.

A spring pressed locking lever I29, Figs, 4 and 5, is provided pivotally mounted at I29 in the frame member 9 and this locking lever is provided with a right angle hook I24 which is adapted to project into the notch I20 to lock the gear II2 against rotation in the operating cycle of the machine. It will be seen in Fig. 19 that the shaft II is split in the frame member so that the short shaft 6| in the bushing II9 rotates only with the parts 59, H9 and III, due to a nut on the end of the stub shaft 6i and the set screw 256 in the disc H9 and the bushing II9.

Extractor mechanism The extractor mechanism for extracting a rolling rod 99 out of a rolled and wrapped calendar 91 is illustrated in Figs. 20 to 23. When a rolled and wrapped calendar reaches the stage in the position of the winding reel shown at as in Fi 3, where the calendar is to be released from the machine, the button or head member 19 in its circumferential travel around the axis of the shaft 9|, by the rotation of the winding reel, moves into the jaws 99 of the extractor bar 99, the latter telescoping in the cylindrical actuator I00. The actuator I has a forlr129 at one end intowhich the head member 19 of the rolling rod' is pulled so that, together with the jaws 99, the extractor device I94 will be able to make and maintain a positive grip on the head member during the extracting and retracting movements. A collar I21 is secured on the other end of the actuator and this collar is provided with apair of pins I29 which are adapted to abutagainst the stop lugs I29 mounted on the frame member 9. A spring I99 abuts at one end against the actuator I00 and surrounds the bar '99 with the other end abutting against an actuatingarm II, which latter is mounted on a threaded pin I92 held thereon by the nut I99.

The extractor device m is shown in its two poandis.

sitions in Figs. 20 and 21, in which, in Fig. 20,

the par-ts are-shown in the position after the discharge of a rolled and'wrapped'calend'ar and retraction of the rolling rod 99 so that the latter 'may'move on in' its circumferential path to reof the bar 99 to the left, to the position'of Fig.

20, is accomplished by the movementof the arm III, which will be explained hereinafter, forcing see ers the her it to the left relative to the actuator I99" which latter ceases its movement to the left when the pins I26 strike against the lugs, I 29.

Pneumatic or hydraulic-system for extractor mechanism The hydraulic system for the extractor mechanism is particularly illustrated in Fig. 23 and details thereof are shown in Figs. 3 and 16 to 18. The extractor device I94, as already referred to, is mounted on the arm I9I which latter is secured on a piston rod I91. The piston rod I31 reciprocates in a cylinder I99 mounted on and supported between two plates I99. These plates I99 may be suitably secured one to each frame member 2 and 9. A piston I40 is secured on the end of the piston rod I9I which reciprocates in the cylinder I99 and the other end of the rod also has a piston I which, however, with its cylinder I42, acts as a buffer or cushioning device to stop the extracting movement of a rolling rod 69 at the end of its movement without jarring or setting up vibrations. The arm vI9l has an extension I49 to which a rod I44 is secured having a piston I45 at the end thereof which cooperates with a cylinder I49. The rod I44 extends through and has a bearing support I49 therefor in the right hand plate I99 and the cylinder I46 is supported on a short rod I" mounted on the other plate I99. This rod I44,

piston I45 and cylinder I49 also acts as a builing or cushioning device to prevent jarring when .the winding rod and extractor device I94 reach the end of the retraction movement.

The cylinder I99 is fed with a compressed fluid, such as 'air, by means of preferably flexible hose connections I49 and I50, one for each end of the cylinder, to successively permit compressed air to enter the cylinder on one side and then the other side of the piston I40. The'flow of compressed air to the cylinder I99 is controlled by a valve I5I which latter obtains its compressed air by means of the flexible hose I52 from any suitable source, not shown.

The valve I5I 'is composed of two parts, Figs. 16 to 18, a stationary sleeve I59 and a movable piston I54, the sleeve I59 being secured by means of a lugi55 to the base I, Fig. 3. The sleeve I59 has two pairs of passages therein, an upper pair I56 for the pipe I 51 connected to the air supply hose I52 on one side and the hose I49 to one end of the cylinder I99, and a lower pair I59 connected to the supply hose I52 and the hose I50 to the other end of the cylinder I99. The sleeve I59 also has two exhaust ports I59. therein. The

movable piston I54 also has t wo passages I90 and I6I extending entirely. through the piston and a pair of part-peripheral passages I62 and I69 which latter cooperate alternately with one and specifically referred to hereinafter.

then the other exhaust port I59 to'exhaust the 'air out of one and then the other side of the piston I40 inthe cylinder I99. The-passages I56 and I are in register altemately with the passages I59 and I6I to feed the compressed air alternately into one end and then the other end of .the cylinder I39. The actual operation of the hydraulic system in timed relation will The movable piston I54 is reciprocated in its cylinder I53 by means of a lever I64 pivoted at I65 at one end and secured in operative position -with the outer end of the movable piston I54.

Near the piston a roller I66 is mounted in the lever I64 and this roller cooperates with a cam I 91, the latter actuating the lever I94 and the be more 7 Drive mechanism The drive mechanism for the machine comprises three main shafts mounted in bearings in the frame members 2 and. 3, Figs. 3 to 5, namely the main drive shaft I69, the cam shaft I and the rocker arm shaft I1I. Themaindrive shaft I69 is split in the bearings I12, Fig. 4, into auxiliary shaft I69 co-axial with themain drive shaft I69. The motor 4 "drives the main shaft I69, Figs. 3 and 4, by means of a chain I13 and the sprocket wheel I14, the main shaft thus driving one part of the clutch I15 of which the other part thereof is connected to the small sprocket wheel I16 which is loosely mounted 'on the shaft I69. The clutch is normally in engagement by means of spring I11, Fig. 2, but when it may be desired to stop the cycle of operations of the machine without cutting off the electric current to the motor 4, the operator of the machine merely depresses the foot pedal I18, which is pivotally mounted to the base I by means of the extension I 19 and is connected to the collar I80 of the clutch I15 by means of the arm, I8I, so that the two parts of the clutch will be separated to cutoff the drive to the sprocket'wheel I16.

The small sprocket wheel I16, Figs. 2 and 4, drives the cam shaft I10 by means of a chain I92 and the large sprocket wheel I83'securely mounted onthe cam shaft I10. The complete cam shaft I10 is shown in Figs. 4 and 5 and comprises numerous cams securely mounted thereon and also a number of other driving elements,

, which will be referred to, as well as a hand wheel I84 which may act as a fly wheel but its main function is to permit a manual setting of the various parts of the machine particularly when starting the machine, with thefoot pedal I18 ,.The-latter has a short rod 200 with a contact rollerl thereon which latter contacts wlthand rocks the locking lever IIO to lockand unlock the winding reel 80 by means of the locking disc I05.

202 is the rocker cam to rotate the auxiliary shaft I69 back and forth by means of a reciprocating rod 203 having one end slotted forming a I link 204 for the shaft I10 with a collar 205 at a rocker arm 206.

depressed, to place the beginning of the cycle of operations in the proper starting order. The cam shaft I10 is also provided with a] belt pulley I85 which by means of the cable 12, Fig. 4, drives the belt 54 to feed the wrapping paper sheets. Also, a small sprocket wheel I86 is mounted on the shaft I10 which is connected to the latter by means of an adjustable pair of discs I81 one of which is secured to the cam shaft I10. A driving chain I98, Fig. 2, may actuate a printing device, not shown, to print any desired identification or address on the wrapping paper.

The cams on the cam shaft I10 are the following, beginning from left to right in Figs. 4 and 5:

I69 is the gear release cam for the large gear I I2and cooperates with the rocking lever I90 pivoted at I9I and having a roller I92 at both ends, of which one rolls on the cam I89 and the other rocks the locking 1 er I23 cooperating with the locking disc II9 fo the 'gear I I2.

I93 is the drive cam for driving the large gear I I 2 and cooperates with the slotted reciprocating arm I94 guided on the cam shaft I10 and reciprocated by the drive cam, said arm I94 rocking the lever I95 connected to the toothed rack bar IIB, the lever I95 beingrotatably mounted on the rocker shaft I1I.

I96 is the reel release cam for releasing the winding reel as the calendars are rolled and cooperates with a rocker arm I91 which in turn rocks the intermediate shaft I98 and a rocker arm I99,

each end of the slot. The other end of the rod 203 is connected, to the shaft I69 by means of g The shaft I69 moves the rocker arm 229, Figs. 19 and, 14, up and down which by means of the link 230 actuates the rocker arm I03 to rotate the winding reel stepwise.

201 is the feed-in cam which actuates the rocker shaft I1I by means of the rocker arm 208 and roller 209 to rotate the shaft I1I clockwise, swing links I0 and move feed table 8 forward, to feed the calendars into the winding reel.

2 I 0 is the return cam which actuates the rocker shaft IN by means of the rocker arm 2 and roller 2I2 to rotate the shaft I1I counterclockwise, swing links I0 and move feed, table 8 backward, Fig. 5, to return the table 8 after each calendar feed.

2I3 is the wrapping paper feed table release cam which actuates to reciprocate a forked lever 2I4 guided by the roller 2I5 and connected to the rocker arm 2I6. The latter is connected to the shaft 2I1 which has a rocker arm2I8 connected thereto ,with the roller 52 which cooperates with the arm 5I secured to the table 41, Fig. 24. y I

2 I 9 is the control cam for thefeed and preparation of the wrapping paper sheets which actuates a reciprocating rod 220 bytmeansof the roller 22I on its periphery and a link 222 connected to a rocker arm 223, the latter being loosely mounted on the rocker arm shaft I1I, Fig. 5. The rod 220 reciprocates in a sleeve 224 secured to a fixed part of the machine frame and actuates a system of interconnected levers 225 to actuate the knife 34 and the supporting means 50, Fig. 1. The rocker arm 223 is adjustably connected to a bar 226 by means of a connecting link 221. The bar 226 is connected to the gear sector 40, which intermittently operates thewrapping paper feed,

and is provided with a slot 228 in whichthe link 221 is adjustably secured, The rocker arm 223 may be supported in its rocking movement by a support 265, Fig. 8.

Miscellaneous details Fig. 15 illustrates a supporting bar 23I mounted on a link 232 which latter is mounted on the shaft 233, to support the calendar and the wrapping paper before they form the convolutions of the roll. I

Figs. 24 and 25 show a guide clip 234 secured on the side guide rail 53 of the feed plate 41, to aid in guiding the calendarsi under the feed plate 91 and into the slot 14 of the winding rods 63.

The rolled and wrapped calendars 91 as they are released from the winding reel fall from the latter into a receiving receptacle 235, Figs. 1a, 3 and 23, located at the back or the side opposite the feed of the calendars, of the machine. Any suitable receptacle, or other means, may be used for this purpose, if desired.

The main base platform I of the machine may be placed directly on the floor, but it is preferable to provide a foot member 236. Figs. 1a and 2. at

each corner thereof which may be adjustable in the platform by means of screws 23!, so that the machine may be placed in a perfectly level position even if the floor thereunder may not be exactly level.

The floating guide bars ll, Figs. 3, to 7 and 27, merge at the ends 238 and slide on the guide bars I! by means of the U-shaped guide 218 secured thereto. The spring pressed ball and socket member I8 is secured to the guide 238, as shown in Fig. 7. The end 238 is also provided with a perforation 248 which is adapted to cooperate with one or the other ball 2, Fig. 6, in the stationary plate 242 having flat springs 243 on the top surface thereof to force the balls 24| downwardly. Each stationary plate 242 is suitably secured to its respective frame member 2 and 3 and is provided with an adjustable stop screw 243, Fig. 6, against which the guide bars l'l abut in their calendar feeding position by means of the ends 238. The underside of the guide bars I5 are provided with a pair of spaced depending lugs 2 and 248, Fig. 27, which cooperate with the ball of the member 18 to maintain the bars I! in their proper positions during the various operating steps and to reciprocate the bars during the successive calendar feeds. An adjustable stop 248, Figs. 3 and 27, is provided on the machine frame for each guide bar l5 which limits the forward movement of the floating table 8. During operation when the calendar feed table 8 is traveling forward to feed a calendar by the fingers l2, the lug 2 strikes the ball socket IS on the end 238 of the guide bars I1 and carries the guide bars forward toward and against a winding rod 83 so that the calendar, by means of its metal bound edge may be positively guided into the shaft 14 in said guide bar. The end 238 of the guide bars is arrested by means of the ball 2 (full line position Fig. 27), but the continued feed of the table 8 and fingers l2 forces the lug 2 past the ball socket l6 until the guide bars l5 strike the stops 246. Upon return movement of the table 8 the lug 244 carries the guide bars back to the dotted line position of Fig. 27, the guide bars ll coming to rest between the lugs 2 and 24!.

Operation The machine operates as follows assuming a manual feed of the calendars to the position where they are successively pushed into the rolling means by mechanically timed elements.

The operator of'the machine first sets the winding reel 88 in position so that one of the winding rods 83 will be directly opposite the calendar feed guides by rotating the hand wheel I84, A calendar 8 is then manually pushed in the direction of the arrow, Fig. 3, under the plate 41 and just far enough so that the metal binding of the calendar is passed beyond the guide fingers l8. The motor is then started, which will carry out the various cycles of operation in timed relationship, dependent upon the operation of the cams, and for which the cams have been given the proper configuration.

The feed table 8 together with the pusher fingers |2 as well as the guide bars II, are moved forward by the cam 201, elements 208, Hi and l0 so that the guide bars I! will be adjacent the slot 13 of the winding rod 63 whereby the bars I! will guide the calendar 8, which is pushed forward by the fingers l4 gripping the metal binding, into the slot 14 so that the latter will grip the metal binding l3 of the calendar. The cam 2|! and elements 2| I, Ill and in now pushes the table 8 and the bars I! back to its original position at the same time that the toothed rack H8. by lever I95 and arm I", starts its upward movement by the cam I93 which will set the gear 2 in rotation to rotate the winding rods 83. The calendar is thus wound to an extent shown in Fig. 15 and before the final winding a sheet of wrapping paper 20 is fed into the partly rolled calendar, the winding reel 60 still remaining stationary.

The sheet of wrapping paper 20 has been previously fed onto the plate 41 by the apparatus shown in Fig. 1, together with the feed belt 54 driven by the cable 12 and pulley I from the cam shaft H8. The sheet of wrapping paper 28 is cut from the web 22 but is provided with strips of adhesive 25 and a tearing string 35 and is printed, if desired, before it is cut into its proper length by the knife 34. The cam 88 through the intermediate members, Fig. 24, that is elements 51, 59, 84, 81, 89 and 88, moves the pin 18 against the edge of the paper sheet 28 through the slots II and positively feeds it into the partly rolled calendar as shown in Fig. 15, at the same time that the table 41 has been tilted downwardly or is permitted to drop down, by the cam 2|3, arm 2, shaft 2|'| and arm 2|3 and after the table 8 and guide bars II have moved back out of the way by cam 2|li, arm 2, shaft Ill and links ID. A final winding and sealing of the wrapping paper now takes place at the same time that the cam I86, arm I91, shaft I98, arm I!!! and lever H0, unlocks the winding reel to permit its rotation counter-clockwise, Fig. 3, while the gear 2 rotates clockwise, bringing the completely rolled and wrapped calendar down to the point Fig. 3, where the reel stops so that the immediately following winding rod may repeat the steps of receiving a calendar and its sheet of wrapping paper. At the point 95 or station, the adhesive on the wrapping paper is given a chance to dry somewhat and it will be noted that the pair of springs 89 for each winding rod will force the roller 82 against the paper and calendar to tightly roll the calendar and effectively seal the wraping paper and the rod 83, by means of the collars 83, is for the purpose of smoothing out the paper and preventing wrinkles forming in the wrapping paper during the rolling thereof. The winding reel, after the winding rod adjacent the feed tables 8 and 41 have received a calendar and wrapping paper sheet, is then given another and repeated V turn to bring thewinding rod and the wrapped and rolled calendar to the point or station 95.

At the point 95 the extractor mechanism comes into operation as follows:

As the rolling rod 83 approaches the point 95 where the rod is to be extracted and the rolled and wrapped calendar is to be released, the head member 19 of the respective rolling rod enters or slides into the jaws 98, Fig. 20, the winding reel comes to rest and is locked against rotation by the members |||l, I85 and I08, and the gear H2 also ceases its rotation to permit the reception of a new calendar and wrapping paper in the winding rod which has arrivedat the feed tables, and to permit the rolled and wrapped calendar at 95' to undergo a preliminary drying period. The cam |6'| then adjusts the valve I53,

Fig. 23, to permit compressed air to flow through hose I49 into the left hand end of cylinder I38 and to exhaust the air from the other end of the cylinder through hose I50, Figs. 17 and 18, to

thereby move the piston I40 and ejector I34 to the right, Fig. 23, to thereby pull the rolling rod 63 out of the rolled and wrapped calendar 91, which latter then drops into the receptacle 235. The valve I53 is then again adjusted by cam I61 to return the piston and rolling rod back into the reel while at the same time anew calendar has been fed into the winding rod opposite the feed tables to repeat the cycles of operation.

In the following, a summarized and brief mode of operation relative to the various cycles of the winding reel will be explained, assuming the machine is started without any calendars in the reel.

In the position'of Fig. 3, with the gear H2 and the winding reel 60 locked against rotation, a calendar is fed into the slot of the winding rod at 95", by means of the metal binding, and the gear H2 is then unlocked and rotated clockwise with the reel still stationary. This will rotate all the winding rods and when the calendar at 95" is wound to the extent as shown in Fig. 15, the wrapping paper is inserted. The winding reel is now unlocked and is rotated counterclockwise a /5 revolution at the same time that the gear is still rotating and continues to rotate clockwiseuntil the rolled and wrapped calendar reaches the station 95 when both the gear and winding reel are again locked. The wrapping paper of the rolled calendar at 95' now undergoes a momentary drying while a new calendar is fed into the immediately following rod at 95" thereupon following again an unlocking of the gear and a rotation thereof clockwise to rotate all the rods. When the calendar at 95" is rotated to roll up to the extent of Fig. 15, the wrapping paper is fed in, the reel is unlocked and rotated, counter to the gear, another V6 revolution. The rolled, wrapped, posted and dried calendar now reaches the station 95 where it is released by pulling out its winding rod, the gear and winding reel having been again locked and the immediately following rolled and wrapped calendar reaches its drying station 95. At 95" the winding rod receives a new calendar and when the release of the rolled and wrapped calendar and the return of the winding rod has been completed at 95, the gear is unlocked and again started its rotation, to repeat the various cycles. It will be noted that during release of a rolled and wrapped calendar at. .95 and a feed of a calendar at 95", all the winding rods are stationary both as to rotary as well as circumferenrial motion. Also, it will be noted that the winding rods after leaving the station 95 proceed empty a revolution of the winding reel before receiving a new calendar to be rolled and wrapped. Thus it would be within the scope of this invention to duplicate the calendar feed means, the wrapping paper feed means, the extractor mechanism and such other operating mechanism on the other side of the winding reel to make it pos-' sible to feed calendars at the station immediately preceding the station 95 to carry out the various cycles in connection with the three winding rods which are empty for the revolution.

From the foregoing it is apparent that the winding reel as well as the gear are alternately locked and rotated during the various cycles and the machine is capable of wrapping as many calendars as it is practically possible to successively feed the calendars manually into the winding reel.

Obviously, the present invention is not restricted to the particular embodiment thereof herein shown and described. Moreover, it is not indispensable that all the features of the invention be used conjointly, since they may be employed advantageously in various combinations and sub combinations. I
